Energy efficient electrical systems, controls and metering

This chapter describes some of the key design features that can reduce carbon emissions arising from the main energy consuming electrical systems, together with the controls and metering systems that can enable energy management across all active building services systems. As with thermal systems, the desired carbon reduction features are a mix of those that control demand to achieve comfort or function; those directly related to minimising losses in distribution between plant and terminal devices; and accepting that there is some overlap between these. The key design decisions are always related to selection of appropriate systems, equipment and distribution arrangements; and inclusion of features to limit demand to that necessary to achieve the required criteria at any point in time.
